Features
• Fourth Generation FemtoClock® NG technology
• Two LVPECL output pairs
• Each output supports independent frequency selection at
19.44MHz, 77.76MHz, 155.52MHz and 622.08MHz
• Two differential inputs support the following input types: LVPECL,
LVDS, LVHSTL, HCSL
• Accepts input frequencies from 8kHz to 156.25MHz including
8kHz,19.44MHz, 25MHz, 62.5MHz, 77.76MHz, 125MHz,
155.52MHz and 156.25MHz
• Crystal interface designed for a 27MHz, 10pF parallel resonant
crystal
• Attenuates the phase jitter of the input clock by using a low-cost
fundamental mode crystal
• Customized settings for jitter attenuation and reference tracking
using an external loop filter connection
• FemtoClock NG frequency multiplier provides low jitter, high
frequency output
• Absolute pull range: ±50ppm
• Power supply noise rejection (PSNR): -95dB (typical)
• FemtoClock NG VCXO frequency: 2488.32MHz
• RMS phase jitter @ 155.52MHz, using a 27MHz crystal
(12kHz – 20MHz): 0.674ps (typical)
• 3.3V supply voltage
• 0°C to 70°C ambient operating temperature
• Available in lead-free (RoHS 6) package
